Access ejb in another websphere

I have installed webpshere in 2 machines. How can I access ejb in the second websphere from servlet in the first websphere?
Thanks in advance

You would have to read up on JNDI to get the InitialContext from the firstWebsphere to get beans from another. Another solution would be using SOAP or JMS to relay information from one to another.

ClassNotFound Exception accessing EJBs in a cluster

I am experiencing some weird behavior when attempting to access EJBs in a
          Weblogic 5.1.0 cluster. The cluster nodes startup fine, and the EJBs are
          correctly deployed. However, when my test client attempts to access them I
          get the ClassNotFoundException listed below. This same client can access the
          same EJBs deployed in a non-clustered environment without any problems, so
          it's definitely related to my cluster configuration. The problem seems to be
          that the client is not receiving the client-side stub. To confim this, I put
          the stub in the client's classpath, and did NOT get the
          ClassNotFoundException. Has anyone else seen this error?
          BTW, I have compiled the EJB both with and without the <home-is-clusterable>
          flag set to true. I get the same exception either way.
          Thanks for any assistance,

Just a side note: I setup the cluster using the WebLogic recommended
          directory structure (see
          http://www.weblogic.com/docs51/cluster/setup.html#676105) and I no longer
          get the exception. I'm still interested in hearing, though, if anyone has a
          scheme for setting up the cluster in a directory that isn't directly under
          the weblogic installation directory.

Lookup ejb in another application in same container

Hi,
The 1012 ejb faq http://www.oracle.com/technology/tech/java/oc4j/1012/collateral/OC4J-EJB-FAQ-101202.pdf states:
"If you want to access an EJB in another application in the same OC4J container you do not have to use RMIInitialContextFactory and you can make the application that contains your application as the parent of your application from your you are trying to access EJBs from e.g. ..."
Question: The FAQ implies that the "parent" attribute is NOT necessary to facilitate this situation and RMIInitialContextFactory may be used - is this correct? I have not found any examples that demonstrate how to do this as elsewhere in the Oracle doco they seem to imply that "parent" must be used (but not in 10.1.3). Can anyone please clarify this and/or what works and what doesn't?
Note: The lookup of remote ejb from another application in same container does work without the parent attribute, its just subsequent calls from a 3rd application or redeploy breaks.
My problem: I get a ClassCastException when :
a) lookup remote EJB (in application A) following redeploy of application B
b) the next invocation of the application A method from client application C
Thanks for any advice,
Paul

Your understanding is correct.
If you make application a to be the parent application of app b; then app b could access app a without using RMIInitialContext.
Also you could use RMIInitialContext to obtain the object without using "parent application" approach, example:
Hashtable env = new Hashtable();
env.put("java.naming.factory.initial",
"com.evermind.server.rmi.RMIInitialContextFactory");
env.put("java.naming.provider.url","ormi://remotehost/bmpapp");
env.put("java.naming.security.principal","SCOTT");
env.put("java.naming.security.credentials","TIGER");
Context context = new InitialContext(env);
Object homeObject =
context.lookup("java:comp/env/EmployeeBean");
For this servlet example, you also need to declare <ejb-ref> elements in the web.xml file:
<ejb-ref>
<ejb-ref-name>EmployeeBean</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>bmpapp.EmployeeHome</home>
<remote>bmpapp.Employee</remote>
</ejb-ref>
In addition, orion-web.xml, must include a mapping from the logical name EmployeeBean to the actual JNDI name where the EJB is bound, as shown in the following example:
<ejb-ref-mapping name="EmployeeBean" location="bmpapp/EmployeeBean" />
Hope this helps,

Error in calling an EJB from another EJB

Hello All,
I have a scenario where i need to call a method of an ejb from another ejb.
Both the EJB's are in different DC's.
EG: DC1 using DC2
I have added the public part of DC2 in DC1.
The following code is written in DC1 to access the EJB of DC2
      MyRemote l_remote;
       MyHome l_home;
       InitialContext l_ctx = new InitialContext();
>>       l_home = (MyHome)l_ctx.lookup("JNDI Name");
       l_remote = (MyRemote)l_home.create();
There is no error at build time and deploy time, but at run time "MyHome" class is not found.
Even i am not able to access the helper class defined in the DC2 at runtime.
Please help.
Thanks in Advance

First off, wrong forum section.
Check if your JNDI name is correctly placed for the bean you're calling -- check j2ee-engine.xml for that. Check the EJB container if the ear file you deployed is there and updated.
Try placing "localejbs/JNDI name" on your lookup parameter.

Jan

Error when One EJB calls anothe EJB

Hi,
I got the following error when I use one EJB call another EJB in OAS 4.0.8.1, the code is developed in JDeveloper 3.0/Win NT 4.0/SP5.
Can anyone give me some ideas? or is there any samples in this case?
Thanks a lot!

Home handle is an object that identifies an enterprise bean. A client may serialize the handle, and then later deserialize it to obtain a reference to the enterprise bean.
The javax.ejb.HomeHandle is similar to javax.ejb.Handle. Just as the Handle is used to store and retrieve reference to EJB objects, the HomeHandle is used to store and retrieve remote references to EJB homes. HomeHandle can be stored and later used to access an EJB home remote refrence the same way that a Handle can be serialized and later used to access an EJB object's remoe reference.
import java.io.*;
import javax.ejb.EJBHome;
import javax.ejb.HomeHandle;
public class WorkingWithEJBHandles {
public static void main( String[] args ) throws Exception {
EJBHome aHome = null;
// get hold of a home interface
HomeHandle handle = aHome.getHomeHandle();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream( bos );
oos.writeObject( handle );
byte[] handleAsBytes = bos.toByteArray();
// store in the database, on file. howwever you want
FileInputStream fis = new FileInputStream( "fileobj" );
ObjectInputStream ois = new ObjectInputStream( fis );
HomeHandle theHandle = (HomeHandle) ois.readObject();
// get back the EJBHome from the HomeHandle
aHome = theHandle.getEJBHome();
// the same kind of logic also holds for EJBHandles, as well as
// HomeHandles
Transfer Object is a Design pattern. Refer to Core J2EE Design Pattern.

I have checked the Sharing and Permissions section of the "Get Info" panel accessed from the Finder and I have set Read and Write Privileges for my user account for Photoshop CS6. System and Admin are also set to Read and Write.
I have a MacBook Pro with OS X Version 10.9.5 and have all available updates for Photoshop CS6, Lightroom 5 and Bridge CS6.

How to access EJB deployed in JBOSS 4 from Creator

Hello.
I am trying to access EJBs deployed on JBOSS in order to develop a web app client, when I import the EJB set from Creator (sessions and entities packages in a jar file) I got the following error message....."No EJB set found in file....." .
I presume there is an kind of xml file description specific for Sun App Server missing. I would like to know if there is other way to expose EJB in creator?....maybe write a config file by hand.
I already read the tutorials related to EJB but those only use pre build EJB jars for Sun App Sserver.
Also I read all the posted about JBoos and EJB in this forum but those are pretty general.
By the way I have Delegate classes to access the EJB. How do I register my delegates in Creator in order to expose their methods?
I�ll really appreciate some light in this matter.
Thanks in advance!!!

Issue in accessing EJB from plain java

Hi,
I am new to OAS. I am using OAS 10.1.2.
I want to access EJB which runs inside OAS, through a plain java program which runs from outside the OAS environment (standalone java program).
I am confused on what to use. RMIInitialContextFactory or ApplicationClientInitialContextFactory for the context in the java program.
what should be the provide URL ?
java.naming.provider.url","ormi://hostname:18140/
is it "ormi" or something else? what is the port number should i use. there are many ports in this OAS. i see that in the console("Ports") link.
also let me know what should i mention in the EJB xml descriptor.
Is this lookup to be done by retrieving from jndi?
pls help.
Thanks,
Sukumar
with this confusion i developed an EJB with the following details
ejb-jar.xml
<ejb-ref>
     <ejb-ref-name>ejb/testDetails</ejb-ref-name>
     <ejb-ref-type>Entity</ejb-ref-type>
<home>com.xxx.xxx.testDetailsHome</home>
<remote>com.xxx.xxx.testDetails</remote>
     </ejb-ref>
orion-ejb-jar.xml
<entity-deployment name="ejb/testDetails" location="ejb/testDetails"
Client Java program
public class testDetailsClient
public static void main(String [] args)
testDetailsClient testDetailsClient = new testDetailsClient();
try
Context context =getInitialContext();
testDetailsHome testDetailsHome = (testDetailsHome)PortableRemoteObject.narrow(context.lookup("java:comp/env/ejb/testDetails"), testDetailsHome.class);
testDetails testDetails;
catch(Throwable ex)
ex.printStackTrace();
private static Context getInitialContext() throws NamingException
Hashtable env = new Hashtable();
env.put("java.naming.factory.initial","com.evermind.server.rmi.RMIInitialContextFactory");

env.put("java.naming.provider.url","ormi://host_name:18140/"); //23791 18140
env.put(Context.SECURITY_PRINCIPAL, "ias_admin");
env.put(Context.SECURITY_CREDENTIALS, "abc123");
InitialContext context = new InitialContext(env);
return context;
if i execute this, it says
javax.naming.NameNotFoundException: java:comp/env/ejb/testDetails not found
18140 is Application Server Control RMI port.
if i run the same code with ApplicationClientInitialContextFactory, it throws exception saying

Hi,
you do not have to package your EJB and PAR together! You can deploy them separately and then reference the J2EE Application from your PAR or vice versa to access it.
For instance you can access the EJB from your PAR as described here:
http://help.sap.com/saphelp_nw2004s/helpdata/en/42/9ddf20bb211d72e10000000a1553f6/frameset.htm
Or you can access a Portal application from J2EE like described here:
http://help.sap.com/saphelp_nw2004s/helpdata/en/42/9ddd0cbb211d72e10000000a1553f6/frameset.htm
Even if you package your PAR in to the same EAR with your EJB they will result in two different containers on the J2EE Engine and you will have to reference them as described in the link above to access the functionality of one component from the other.
Best regards,
Stefan Brauneis
